I had the same problem and found out I was sold the wrong sensor, my 4.0 has four, they are all different, when you install a new sensor, you must make sure you clear the trouble code before you start the engine, ignition on engine off, that should do it, it worked for me, also if you have your own scanner and can erase the codes yourself, the wrong 02 sensor will turn engine light on with cold start, then after I erased the code it would stay off all day until the next cold start, thats when I found out my new 02 sensor was for bank 1 sensor 2, and not bank 2 sensor 1, hope this helps

O2 sensors are tricky. sometimes like anything else they fail. many times though the exhaust mixture they encounter is out of their range and that shows up as a failure.since you seem to have no other problems , I would go ahead and change them, but don't be disappointed if the code shows up again (at least you know it's not the sensors.) I don't like using the process of elimination when doing repairs but sometimes you must.

Try removing the negitive cable from the battery for 5 minutes. Hook it back up and start the car. Let it warm up and then drive it normally for 2 or 3 miles. Then recheck for the codes.

My jeepliberty will crank but not fire. error code 135 BANK 1 AND 155 BANK 2?


If they are codes P0135 and P0155 they refer to both O2 sensors nearest the engine on the exhaust. The ones before the catalytic converter on each exhaust pipe.
P0135 = O2 Sensor Heater Circuit Bank 1 Sensor 1
P0155 = O2 Sensor Heater Circuit Bank 2 Sensor 1

Why the codes po125 & po135 &po155 keep coming back?


Hi there:

DTC P0125 - Insufficient Coolant Temperature For Closed Loop Fuel Control

The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is likely going to be the result of the above causes (faulty thermostat, faulty ECT sensor, or a low coolant level).


DTC P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
or
DTC P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)

A code P0135 and P0155 may mean that one or more of the following has happened:

  • O2 Heater element resistance is high
  • Internal short or open in the heater element
  • O2 heater circuit wiring high resistance
  • open or short to ground in the wiring harness

In order to solve just...
  • Repair short or open or high resistance in wiring harness or harness connectors
  • Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)


  • Hopoe this helps.

    I'm thinking about buying a 2002 range rover. It has a service/check engine codes of 134,135,155. Is it likely to be more than oxygen sensor problems? Please reply , Mel


    with those codes showing, it could be either bad O2 sensors or there is a problem with the wiring to those sensors. Also, the wrong sensors may be installed. I'm assuming codes P0134, P0135, P0155.

    For others viewing this:

    P0134 = O2 sensor circuit-no activity detected (bank 1 sensor 1)

    P0135 = O2 sensor heater circuit malfunction (bank 1 sensor 1)

    P0155 = O2 sensor heater circuit malfunction (bank 2 sensor 1)

    P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)

    if you aren't getting the corresponding bank 1 sensor 1 code, P0135, you may have gotten the wrong O2 sensor, or perhaps it is defective? There is the chance that if you put some anti-seize on the O2 sensor threads or on the exhaust threads that you may have gotten something on the sensor itself clogging it up....

    I believe sensor 1 is pre catalytic converter, but this code refers to the internal heater in the O2 sensor... so if all else fails, you may just have to buy or exchange for another and see if it helps your problem
